EQ Shape Coresc311d6ca-456e-4e11-aa9a-f28a6cc96381.jpg

Magnetics introduces EQ powder cores for telecom rectifiers and Hybrid, Plug-In Hybrid, and Electric Vehicle on-board chargers.

EQ cores are a cross between E cores and pot cores. Similar to pot cores, the round centerpost of EQ cores offers minimal winding resistance, ideal for heavy gauge wire, while its planar shape facilitates low profile, compact design. In comparison to E cores and other non-planar cores, EQ powder cores offer better space utilization, shielding and improved thermal performance.

Custom heights and matching I cores may be available upon request. Contact Magnetics with custom designs.

LP cores are similar to EQ cores but with larger wireways for easier winding an assembly. View Magnetics' LP Cores page.
